Specification of Letters Patent.-

Application filed August 18, 1906. Serial No. 381,187.

To all whom it may concern:

Beit known that I, J OHN Rosin, a subject of the King of the UnitedKingdom of Great Britain and Ireland, and a resident of 66 Albertstreet, Edinburgh, in the county of Midlothian, Scotland, gas-engineer,have invented new and useful Improvements in Automatic Gas Lighters andExtinguishers, of which the following is a specification.

This invention relates to improved means for auto matically lighting andextinguishing gas lights, by varying the pressure in the mains.

In the case of a single burner, I conduct near thereto a pilot burnerfrom which the burner prop er is ignited; the pilot light also beingignited from the burner proper that is to say that simultaneously withthe extinguishing of the gas burner the pilot burner is lighted andsimultaneously with the extinguishing of the pilot burner the gas burneris ignited.

Figure 1 is a sectional elevation of my improved means for automaticallylighting and extinguishing gas lights. Fig. 2 is a sectional plan takenon line 1, 2 of Fig. 1. Fig. 3 is a sectional elevation of Fig. 1, atright angles thereto. Fig. 4 is a detail hereinafter referred to. Fig. 5is an elevation of another form of my improved means for automaticallylighting and extinguishing gas lights; certain portions being brokenaway. Fig. 6 is a plan of Fig. 5. Fig. 7 is a sectional elevation of aportion of Fig. 5. Fig. 8 is an elevation of another form of my improvedmeans for automatically lighting and extinguishing gas lights. Fig. 9 isa plan of Fig. 8. Fig. 10 is a detail, hereinafter referred to.

Refeiringto Figs. 1 to 4 of the drawings, the apparatus consists of asmall gasometer A, the dome of which is weighted to remain down withnormal pressure in the main and by increasing the pressure in the main,the gas is lighted or extinguished. The gasometer is provided with anannular space a into which the depending portion of the gasometer A isinserted; the said annular space a being provided with a mercurial orother seal. Gas is conducted through the pipe B upwards into thegasometer A and also into the gas sealing chamhere 0 and D as shown moreparticularly in Fig. 4 which is a section of the said sealing chambers.

When the gas enters the gasometer A through the pipes B and b, it isalso conducted into thebranch pipes b shown more particularly in Fig. 2,the said branch pipes communicating with the sealing chambers C and D atb Fig. 4 and the arrangement is such that the pressure of gas enteringthe gasometer A from the mains, causes the dome thereof to ascend. In sodoing, one or other of the supply pipes c, d are unsealed and gas isallowed to flow out of one of the sealing chambers C, D,thence throughthe pipes to either the pilotlight or the gas light proper. The pipes c,(I depend within the sealing chambers O D shown more particularly inFigs. 1 and 4. It will be observed that in Fig. 4 the opening of thepipe 0 is sealed, therefore there is no gas supply there-through; gashowever is being supplied through the pipe d by reason of the end of thesaid pipe being unsealed. When the sealing cups are in the halfposition, gas for the moment enters both pilot pipe and gas light pipeso as to allow one light to ignite the other before cutting off thesupply to either of the two pipes.

To effect the actuation alternately of the sealing and unsealing ofthepipes c, d, I connect to the dome of the gasometer A the rod 6 whichis elevated and lowered by the action of the dome of the gasometer. Thisrod has attached to it a radial arm 6 which is caused to rise and fallwith the rod 0. In so doing it engages with one or other of the arms E,F at their hook-shaped ends f. These arms are connected to the sealingcups E and F so that they are capable of raising and lowering the saidsealing cups which are provided with a mercurial or other seal. Attachedto the bottom of the arms E and F is the half disk G pivoted to the saidarms at g. This half disk is pivoted to the bracket 5 secured to thebottom of the gasometer and shown more particularly in dotted lines inFig. 4.

Secured to the top ,of the half disk G is a pin g projeeting out fromthe face of the said half disk and loosely pivoted to the said pin isthe wire tumbler H which is provided With a counter-balance it below thepivot or pin 9 and the arrangement of the counter balance h and tumblerH is such that the counter-balance always keeps the tumbler in aperpendicular position irrespective of the position of the half disk Gby which it is carried.

Fig. 4 shows the relative position of this tumbler and counter-balancewith the half disk G.

Depending from the fixed bracket j, as shown in Fig. 1 and moreparticularly in Fig. 3, is the guide rod 7' to keep the radial rod 0 inposition while the said rod is elevating one of the arms E or F. Thetumbler H performs the function of altering the position of the radialrod 6 so that it engages with the hook-shaped portion f of one or otherof the arms E, F that is to say the bottom of the tumbler where the rode is resting in, as shown in Fig. 1, is transferred to immediately belowthe hook-shaped portion f of one of the arms E, F, or in other words therod 6 as it descends follows ation in the position of the tumbler beingeffected as hereinbefore referred to, by altering the position of thehalf disk G by which it is carried.

/ Fig. 5 is another arrangement with all the various motions asdescribed with reference to Figs. 1 to 4, but instead of employing sidearms such as E and F hereinbefore described and having cups such as Eand F, I provide arms K which are mounted over the top of the sealingchambers L and L Figs. 5, 6, and 7,

- the contour of the inside of the tumbler H. This alterthe actuatingrods Z, Z being inserted through the top of the said arms K and beingcarried thereby.

Referring to Fig. 7, the gas enters through the main into the pipe Mthence through the small ports minto the sealing chambers L, Lthence outthrough the ports m into the gasometer so as to actuate the rising andfalling dome thereof. The left hand side of Fig. 7 shows the pipe Nunsealed by its sealing cup n, the other pipe N being sealed by its cupn Referring to Figs. 8 and 9 which shows an arrangement for allowing oneof two gas burners to be lighted and with the pilot lightextinguished-either one or other of the two burners may be lighted andthe apparatus is capable of effecting a round of motion.

As shown in Fig. 9, I employ the three cylinders P, Q and It and Iprovide three half disks p, q and 1" each of which has a counter-balancearrangement similar to that shown in Fig. 5 and each of the saidcounterbalance arrangements are provided with the actuating rods p (1and 1' as shown. These rods are caused alternately when-elevated, bymeans of the central rods S, to engage with one of the hooked arms P, Qor R to which the rods for sealing and unsealing are attached (theserods are not shown in.this arrangement; the sealing cups or rods beingsimilar to those shown in Fig. 7.)

In the detail Fig. 10, which is a sectional elevation of centralactuating rod connected to the dome, I employ a seal as shown so thatgas cannot get access to the works. v

The rising and falling rod 8 is provided with the sleeve 8 the flange sof which is secured to inside of the dome of the gasometer andwiththe-lower portion 3 dipping into the seal cup s and being sealedthereby; therod s rising and falling within the said sleeve.

In each and everyone of the appliances the actuation of the rods forlifting the arms is effected and gov erned by the canting of the halfdisks and tumblers.
